BATTERY SETS
The 12530/15240 control unit is designed to use only sealed lead-acid or equivalent batteries for back-up
power. Attaching a close-coupled battery box, if required, may use battery sets beyond the physical
capacity of the enclosure (10 AH).
AUXILIARY MODULES
Remote LCD Annunciator
The Faraday 12506 remote LCD annunciator consists of a backlit 80 character LCD alphanumeric
display, 4 menu buttons, 4 dedicated buttons for operator interaction, 6 LED indicators, and a security
key-switch. The display and controls on the annunciator are the same as those on the front of the control
unit, including a key-switch for security. The back light operates only when the data are being accessed,
to conserve power.
Up to sixteen annunciators may be addressed by the communications circuit, but some may require
12408 auxiliary power supplies, depending on the total accessory power loading.
Serial Relay Unit and Serial Relay Extender
The Faraday 12507 includes a processor board and a relay board. The processor board receives
commands from the control unit for activating the relays and transmits supervision and control functions
to the control unit. The processor board can control up to 3 relay boards. Each relay board provides 8
relays with form C contacts. The control unit can address up to 8 Serial Relay Units and/or Serial
Annunciator Units. Faraday 12408 auxiliary power supplies will be required to power units beyond the
control unit capability.
Serial Annunciator Unit and Serial Annunciator Extender
The Faraday 12509 includes a processor board and an annunciator driver board. The processor board
receives commands from the control unit for activating the outputs and transmits supervision and control
functions to the control unit. The processor board can control up to 4 annunciator driver boards. Each
driver board provides 16 supervised outputs for LEDs or incandescent lamps. The control unit can
address up to 8 Serial Relay Units and/or Serial Annunciator Units. 12408 auxiliary power supplies will
be required to power units beyond the control unit capability.
Network Interface Board
The Faraday 12523 Network Interface Board provides an interface between the associated control unit
RS232 connection and an MPC-NET network. The Network Interface Board is powered from the control
unit auxiliary power output. For further installation instructions, see the MPC-NET manual P/N 447259.
Auxiliary Power Supplies
The Faraday 12408 Auxiliary Power Supply can be used to provide additional power for notification
appliance circuits. The 12408 has two 1.5A power-limited outputs and a trouble relay contact for
monitoring by the control unit.
